No Shadows in 3D View - Hardware Acceleration

[reidweber]

Hello, I recently upgraded to Archicad 26. Originally, I accidently downloaded the INT version of Archicad instead of the USA and was working in that file for about a week. I then realized the error and downloaded the USA version and opened the file.  I'm now finding that none of the 3D views are casting shadows while in the Accelerated Engine.  I've looked at the obvious spots like checking "shadows" are on under 3D styles, the sun angles, and sun options. Are there any other places to check that may have shadows turned off? See the before and after below and my settings screenshotted.

Thanks,

Reid

I opened it up today and the shadows have returned. Should have started with the ol' restart method first. Thanks.

Same here! I closed the model and opened and it worked, the shadows showed up again.

How strange. I found the same issue, jumped on here and tried closing and re-starting. Walla resolved!

I'm on ArchiCAD 29, now facing the same problem, Closed and open again, restarted PC and opened again, still no Shadows. But only in one specific Project, other projects have shadows working. I ran a Sun study, and after that my Shadows disappeared.
Then I found something that did bring back the shadows. With this setting on, NO shadows.

Hope it helps someone.
